Tipping a crate

    1. The problem statement, all variables and given/known data

    I have been trying this question since 5 hours but I am lost ! Any help would be appreciated

    Some moron kids are trying to tip over a storage bin as shown. The bin weighs 7100 N, w = 2.2 m, h = 3 m, d = 1.6 m, and theta = 20 degrees. With what force do they need to push in order to tip the bin over?
    F= ? Newtons
    If the coefficient of friction between the box and the floor is 0.43, calculate the force of friction on the box and determine whether it will slide or tip over
    Tip or Slide?

    2. Relevant equations
    ΣT = 0

    3. The attempt at a solution
    now what??

    Re: PLease help ASAP.

    When you do these problems it is helpful to describe what you are doing in words - if nothing else, it focusses you mind on the physics.

    What sort of motion does the box have to undergo to get tipped? Where is the pivot?
    Where does the main force opposing the tipping act? In which direction?
    After that it is a matter of torques and reason - though you could try doing it in terms of conservation of energy.
